1. Tape Speed Adjustment
Settings: • Test tape : TTA–100 (Tape center)
• Test point : PHONES (J101)
• Adjustment location : SFR101
• MSP : CLASSIC
• TAPE SELECTOR : NORM
• VOLUME : MAX
Method : Play back (FWD) the test tape and adjust
SFR101 so that the frequency becomes
3010Hz ± 10Hz. Then confirm WOW is less
than 0.50%.
2. Dolby Level Adjustment
Settings: • Test tape : TTA–200
• Output test point : Dolby test point
TP1(Lch),TP2(Rch)
• DOLBY NR : OFF
• TAPE SELECTOR : NORM
Method : Play back (FWD) the test tape and adjust
SFR103 (Lch) and SFR102 (Rch) so that the
test point becomes 100mV ± 1 dB.
3. GOVERNER Adjustment
Perform the STOP —> PLAY and REVERSE operations
(or PAUSE ON —> OFF) after the motor is replaced.
When the tape starts running smooth, this adjustment
is not necessary. If wow is conspicuous at the beginning
of the tape-run, perform this adjustment following the
procedures below.

Solder
1) Solder resistor pattern (A) of the MOTOR AND
GOVERNOR MATCHING ADJ. resistor group.
2) Set the tape speed (using speed adjustment SFR101).
3) Restrict the motor rotation by hand (or turn PAUSE ON).
4) Remove your hand and listen to the beginning of the
tape-run.
5) When the rise of tape running is smooth, no more
adjustment is necessary.
If wow continues for 1 to 2 seconds at the rise time,
changethecombinedresistance according to procedure
6 and check that the tape starts running smooth.
6) Solder the resistor pattern according to the table below
(NOTE : =10ohm , =2.7ohm , =4.7ohm)
7) Finally re-check the tape speed.
Caution : Cool the patterns down to normal tempera-
ture after soldering. If the pattern remains
heated, the gorvernor circuit does not opeate
normally.
